We used these modules during an overnight migration from separate dark-fiber links to a CWDM-based design. The key requirement was an 80km 1370nm SFP that could operate reliably with our existing single-mode fiber plant and provide diagnostics to the NOC. Once installed, the DOM readings helped us verify splice-loss assumptions without rolling a truck to every remote site. The 1G CWDM optics have stayed stable through normal traffic peaks, and the Duplex LC format made replacement work quick for the field team. Highly recommended for long-distance gigabit CWDM applications.

We used this 1G 1370nm CWDM SFP to extend a connection between two office sites over existing single-mode fiber. The 80km rating gave us enough margin for our route, and the DOM values were visible from day one. Great fit for a practical enterprise fiber network build.

We needed a 1370nm single-mode SFP for a remote network cabinet connected to an indoor core room through a long metropolitan fiber route. The site was still within commercial operating conditions, but it experienced regular daytime temperature changes. This 1G CWDM optic maintained steady optical readings and clean connectivity throughout our monitoring period. The 80km distance capability also gave us enough allowance for connector loss, fusion splices, and future maintenance margin.

We deployed 24 LS-CW371G-80C CWDM modules across a municipal campus fiber network using 1370nm as one channel in a passive CWDM system. The longest live route is just under 67km including patch panels and splices, so the 80km optical budget was the right class for the job. Every module established a stable 1.25Gbps link over single-mode fiber, and DOM monitoring let us compare transmit and receive levels before and after the cutover. That made fault isolation much easier than working with non-DDM optics.

Our operations team used this 80km CWDM SFP during a fiber resilience project between two production facilities. We ran acceptance tests with long-duration traffic, link-state monitoring, and repeated module reseating before putting the circuit into service. The Duplex LC interface was convenient for our existing patch frames, and all modules reported normal temperature, voltage, TX power, and RX power through the switch diagnostics. No intermittent alarms or unstable links after deployment.

We installed these LS-CW371G-80C 1370nm CWDM SFP modules for a regional security network connecting several remote camera aggregation sites back to the control center. Most paths were between 52km and 68km over single-mode fiber, with passive CWDM equipment already in place. The 1.25Gbps links stayed stable during continuous video traffic, and the DOM data gave our NOC useful visibility into optical receive levels. Great option for extending legacy 1G infrastructure without adding new fiber pairs.
